S&W M&P 15-22 blows up???

so I'm out shooting some cci quiets and decide to shoot a few aguila sub-sonic rounds, first few rounds shoot fine then it's like a mini explosion by my head, I'm guessing it fired out of battery??? casing looks real funky, it blowed out a spring and my extractor not sure what else is messed up. thankfully it did not hurt me or my brother. it was LOUD my ears are still ringing.

do you guys have any idea on what happened??
and how do i go about fixing it? I figure on calling or emailing smith and wesson tomorrow

I thought the super quiets and other types should not be shot out of a rifle?

Since some of the projectiles are powered by priming compound only, they might be subject to not leaving the barrel every time.

In rimfires, it's not unheard of for the extractor to set off the primer while chambering.
Any instance where it 'hit' the rim due to being fouled either under the extractor or at the breech face, a jammed ext spring (holding it down) could be enough to set off the primer.

Yeah, and it doesn't have a bolt hold open which renders it useless as it doesn't keep with the correct manual of arms like the M&P15-22 does. I would trade my CMMG dedicated upper for a M&P15-22 anytime.

I am thinking similar to Berto........only I suspect the extractor failed first and caused the OOB.

The good news is that S&W customer service is usually very good with shipping and repair gets it fixed quickly.

Good luck. Mine has probably 1500-2000 rounds without issue.
